A nurse is assessing a client's cranial nerves as part of a neurological examination. Which of the following actions should the nurse take to assess cranial nerve III?
Eliciting the gag reflex
Testing visual acuity
Observing for facial symmetry
Checking the pupillary response to light
The Correct Answer is D
Choice A: Eliciting the gag reflex is a way to assess cranial nerve IX (glossopharyngeal) and X (vagus), which are responsible for the sensation and motor function of the pharynx and larynx.
Choice B: Testing visual acuity is a way to assess cranial nerve II (optic), which is responsible for the sense of vision.
Choice C: Observing for facial symmetry is a way to assess cranial nerve VII (facial), which is responsible for the motor function of the facial muscles and the sensation of taste.
Choice D: Checking the pupillary response to light is a way to assess cranial nerve III (oculomotor), which is responsible for the motor function of most of the eye muscles, including those that control pupil size and lens shape.

Correct Answer is C
Explanation
Choice A: Contacting the provider for further orders is not necessary, because the client has type AB blood, which is compatible with any other blood type. The client can receive type B blood without any adverse reactions.
Choice B: Notifying the blood bank of the discrepancy is not required, because there is no discrepancy. The blood bank sent the correct type of blood for the client, according to their blood type.
Choice C: Administering the blood as ordered is the correct action, because type B blood is compatible with type AB blood. The client will not have any transfusion reactions or complications from receiving this type of blood.
Choice D: Completing an incident report is not appropriate, because there is no incident. The nurse did not make any error or mistake in administering the blood to the client. There is no need to document or report anything unusual.

Correct Answer is D
Explanation
Choice A Reason: Dextran 70 is not a medication that the nurse should plan to administer for a client who has a traumatic head injury and is exhibiting signs of increasing intracranial pressure. Dextran 70 is a plasma expander that increases the blood volume and viscosity, which can worsen the intracranial pressure by increasing the cerebral blood flow and edema.
Choice B Reason: Hydroxyethyl starch is not a medication that the nurse should plan to administer for a client who has a traumatic head injury and is exhibiting signs of increasing intracranial pressure. Hydroxyethyl starch is another plasma expander that has similar effects as dextran 70, and can also increase the risk of coagulopathy and renal failure.
Choice C Reason: Albumin 25% is not a medication that the nurse should plan to administer for a client who has a traumatic head injury and is exhibiting signs of increasing intracranial pressure. Albumin 25% is a colloid solution that increases the oncotic pressure and draws fluid from the interstitial space into the intravascular space, which can also worsen the intracranial pressure by increasing the cerebral blood flow and edema.
Choice D Reason: Mannitol 25% is a medication that the nurse should plan to administer for a client who has a traumatic head injury and is exhibiting signs of increasing intracranial pressure. Mannitol 25% is an osmotic diuretic that reduces the intracranial pressure by creating an osmotic gradient and drawing fluid from the brain tissue into the blood vessels, which can then be excreted by the kidneys. The nurse should monitor the urine output, serum osmolality, and electrolytes when administering mannitol 25%.
